我正在使用RichFaces 4.1,我找到了我的模板,如下所示:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:a4j="http://richfaces.org/a4j">
<h:head>
<title><ui:define name="title">Application Title</ui:define></title>
<meta http-equiv="content-type" content="text/xhtml; charset=UTF-8" />
</h:head>
<h:body>
<ui:insert name="body">Default content</ui:insert>
</h:body>
</html>
它总是为我添加额外的头部信息:
<link type="text/css" rel="stylesheet" href="/org.richfaces.resources/javax.faces.resource/org.richfaces.staticResource/4.1.0.Final/PackedCompressed/DEFAULT/skinning.css" /><script type="text/javascript" src="/javax.faces.resource/jsf.js.jsf?ln=javax.faces"></script><script type="text/javascript" src="/org.richfaces.resources/javax.faces.resource/org.richfaces.staticResource/4.1.0.Final/PackedCompressed/packed/packed.js"></script>
如果我从模板中取出这部分,那些额外信息将会消失:
<h:head>
<title><ui:define name="title">Application Title</ui:define></title>
<meta http-equiv="content-type" content="text/xhtml; charset=UTF-8" />
</h:head>
使用额外的信息,页面呈现得更好,但是如果此页面基于表单操作的值返回(如faces-config.xml中定义)导航到下一页,则组件(例如a4j:commandButton)将不起作用,需要点击两次才能运行。
这是一个错误吗?如果你去richfaces展示并打开源代码,那么head的元信息就是diff。任何理想我为什么会得到那些看似错误的额外元信息...

感谢您的建议,但没有帮助...

正如你在faces-config中看到的那样,在用户点击p.xhtml上的按钮后,它将转到resetpwd.xhtml,如果我在模板中定义了,那么resetpwd.xhtml上的按钮将不起作用没问题,我需要点击两次然后处理请求。好吧,如果我直接去resetpwd.xhtml去throgh p.xhtml,一切都运转良好。
所以我怀疑问题是由...在模板中定义的。使用这个xml元素,页面源会显示额外的标题信息:
必须是richfaces状态管理中的一些错误或头部中包含的额外元信息。如果我直接转到resetpwd.xhtml,一切正常(即该页面上的按钮无需点击两次即可响应)。如果从p.xhtml导航到resetpwd.xhtml可以正常工作,如果从tempalte文件中取出...,但如果我这样做,那么页面将无法用皮肤渲染。
